The utility model solves the technical scheme that its technical problem adopts: a kind of high frequency transformer, comprise " work " font magnetic core, in the middle of described magnetic core, be wound with coil windings, described magnetic core has the U-shaped framework that two openings can be involutory outward, is respectively U-shaped framework and lower U-shaped framework; Described two U-shaped frameworks surround described magnetic core involutory connecting as one; Two end walls of described magnetic core are supported respectively at described U-shaped frame inner wall, and described framework is provided with metal joint, has the end of a thread to draw and be connected on metal joint in described coil windings;
Above-mentioned coil windings comprises armature winding and secondary winding, between armature winding and secondary winding, is provided with insulating tape, and one end of described insulating tape exceeds the edge of armature winding;
The middle part of above-mentioned " work " font magnetic core is winding section, and described armature winding is directly wound on winding section, and described insulating tape exceeds the one end at armature winding edge for the secondary winding of coated armature winding and secondary winding infall;
The outside of above-mentioned two U-shaped frameworks pastes the crashproof layer of one deck, and described crashproof layer is fiber board.
As the preferred material-structure of above-mentioned insulating tape, described insulating tape is epoxy adhesive tape.
As a kind of preferred implementation of above-mentioned insulating tape structure, one end, bottom of described insulating tape exceeds the bottom margin of armature winding.
A kind of high frequency transformer described in the utility model, it has the following advantages:
The utility model high frequency transformer adopts two U-shaped frameworks that involute to fix magnetic core, makes the structure of whole transformer more simple, and volume reduces, weight saving; Meanwhile, U-shaped framework outside has pasted crashproof layer, and transformer is provided with, and U-shaped framework covers with the extraneous uniform crashproof layer in the position of colliding with that easily contacts; The utility model also by armature winding and secondary winding by the insulating tape separation of insulating, coil windings is in winding process, first coiling armature winding, armature winding is close to winding section coiling, after armature winding coiling completes, by insulating tape exceed end reflexed, the edge of secondary winding is coated, insulating tape carries out electric insulation to armature winding and secondary winding.
